JWH-175 is a drug from the naphthylmethylindole family which acts as a cannabinoidreceptoragonist. It was invented by the scientist John W. Huffman and colleagues at Clemson University. JWH-175 is closely related to the widely used cannabinoid designer drugJWH-018, but with the ketone bridge replaced by a simpler methylene bridge. It is several times weaker than JWH-018, having a binding affinity at the CB1 receptor of 22nM, though some derivatives substituted at the 4-position of the naphthyl ring have potency more closely approaching that of the equivalent naphthoylindoles.[1] This makes JWH-175 considerably less potent than most synthetic cannabinoid drugs used in synthetic cannabis blends, and it is unclear if JWH-175 has ever been used for this purpose. However it has still been explicitly banned in several jurisdictions including Russia and some Australian states, in order to stop its potential use as an ingredient in such products.
